synaptic also shows no virtualbox installed, but I have virtualbox in the menu and it works fine, just version 3.2.12. With no virtualbox pkgs marked in synaptic, I just marked getvirtualbox as "mark for installation" and applied. I now have it as marked installed but for verssion 3212, with no other boxed marked. I can't uninstall VB if it tells me it is not installed.
